If you are looking for modern cordage that stands up to just about any job - tackles, loops, halyards - Ocean 3000XG, made of pure Dyneema SK78 and treated with FSE Robline's S.Y.I.S. technology, stands out.
A step up from the original Ocean 3000, Ocean 3000 XG uses SK78 instead of SK75, and should offer lower creep than Ocean 3000, but with the same strength.
Ocean 3000XG high breaking strength, low weight, and S.Y.I.S. resistance to UV deterioration and abrasion, make it a perfect fit on any race boat.
• Perfect for applications where light weight, high strength and low stretch are critical
• Single braid 12-plait Dyneema SK78 line
• Treated with the unique S.Y.I.S. lightweight polyurethane impregnation system for high abrasion resistance and UV protection
Heavy on the technical side...
Dynema® is the Dutch company DSM Dyneema's brand of UHMWPE (Ultra High Molecular Weight PolyEthylene fiber), a long chain, high strength, oriented strand, synthetic fiber with very high strength as well as high abrasion resistance.
This fiber is also known as HMPE (High Modulus PolyEthylene).
Dyneema is available in a number of formulations, SK-60, SK-75, SK-78, SK-90, etc. Each progressively stronger and more expensive.
Of particular interest these days is the difference between Dyneema SK75 and SK78. Dyneema SK78 has the same high strength of SK75, but with lower creep (non-recoverable stretch).
Honeywell International produces a similar UHMWPE fiber, marketed as Spectra®
